Hi, thanks your hand for making some features free for whom may not buy the original.I have a TOYOTA RAV4 2017 here in Iran. I downloded and did all processes but it does not work. It has not SD holder but DVD for navigation and i dont know what the device software is. Windows ce or Android? By transferring file "navigation" to DVD and getting into the device, nothing is happening there and it takes back DVD. Please help me know which software and how to install and run it correctly. Thank you
